How do you make dim su pastry?

To make dim sum pastry, combine all-purpose flour and boiling water, stirring until it forms a rough dough. Knead the dough until smooth and elastic, then cover and let it rest for about 30 minutes. Roll the dough into thin rounds and fill with your choice of fillings, such as minced pork, shrimp, or vegetables. Finally, steam the filled dumplings until cooked through, typically for about 10-15 minutes.
